multimine-1.20.1.2
forge 47.2.0

I can't reproduce this with 1.20.1.2 and 47.2.0 in my dev env. Are you doing something specific?

I started mining a tree block, shifted blocks while mining, stopped, then started again. I dont get any strange behaviour like you.

You can also go into multimine.cfg and change debugMode to true. Now your logfile will contain all the MultiMine events and telegrams

If you can reproduce the bug within 3 seconds or so and give me the logfile for that timeframe, i could have a look there

Thanks, i think i figured out what the issue was, but since i cant reproduce it, please see if this fixes it for you:
multimine-1.20.1.3.zip
Rename the ending to .jar and replace your multi mine with it

For the record:
Progress tracking was not properly reset when switching blocks
You mined one block to a high progression, then another to a low progression, and Multi Mine did not deem it necessary to store the lower progression of the second block as the "last known" progression was higher

latest.log

sorry for taking a while to respond. I've also removed all mods except for Multi Mine, but it's still happening.
Let me know if you need more info on this.

The issue is gone with the new version you provided! Thank you for being so quick to fix it!

Fixed it in both the 1.20 branches and pushed new versions to curse. Case closed
